Five freediving destinations carry real weight in the global community. Each offers something distinct – a record-setting depth, a world-class school, a wall to drop down, a cave system to swim through. One of them has earned a name nobody wants attached to a dive site. We will get there.
1 – Dean’s Blue Hole – Bahamas.
On Long Island in the Bahamas, in a quiet bay protected by a sand cay, sits the second-deepest known blue hole on the planet. 202 meters to the bottom. Crystal-clear water. Almost no current. A vertical column you can drop down in a single straight line without thinking about anything but your body.
This is the venue for Vertical Blue, the annual depth competition that William Trubridge founded in 2008. It is where Trubridge set his CNF (constant weight no fins) world record of 102 meters in 2016. It is where most of the world’s elite freedivers come to train when they are preparing for a record attempt. The water is warm. The depth is honest. The conditions are about as predictable as open-ocean freediving gets.
For a serious recreational diver, Dean’s offers what almost no other site does: a long, deep line you can train on in safe conditions, with the world’s best safety divers and judges in the water around you during the comp season. Outside competition windows, the hole is available to whoever shows up with proper training and a buddy.
Season: April through early June for Vertical Blue (the competition window — the platform, judges, and safety infrastructure are all there). Year-round otherwise, with the calmest seas November through May.
Access: Fly to Long Island via Nassau. Small operators run depth training out of the Greenwich Settlement area. Plan three to seven days. This is not a one-day stop.
2 – Dahab Blue Hole – Egypt.
On the Sinai Peninsula, a hundred kilometers from the Israeli border, sits the single most photographed dive site on earth. A near-perfect cylindrical sinkhole in the reef, dropping straight down to 100 meters where a submerged arch opens out into the open Red Sea at 56 meters depth.
The blue hole itself is breathtaking. The water is warm year-round. The reef wall on the way in is healthy. Freedivers come here in numbers because the depth is right there, the line is consistent, and the surface conditions are usually calm. Several established freediving schools operate within walking distance.
And this is the part you should know before you book the flight: the Dahab Blue Hole has another name. The Diver’s Cemetery. Estimates vary, but the consensus number from local instructors and Egyptian dive authorities is somewhere between 130 and 200 divers killed at this site over the past three decades. The plaques are mounted on the cliff face above the hole. You can read the names. Several are added every year.
The deaths are not random and they are not the freediving population. The overwhelming majority were scuba divers attempting “the arch” — descending from the inside of the hole and trying to swim out through the submerged tunnel at 56 meters depth. The arch is a 26-meter horizontal swim at depth, in low visibility, on scuba, with no easy exit. Divers without the right training, gas, or buddy support get narcosis, lose orientation, and run out of bottom time before they can navigate out. Many were diving on standard air, well past safe recreational limits.
For freedivers, the blue hole is a different proposition. The vertical line in the center of the hole is one of the cleanest training environments in the world. The depth is honest. The conditions are predictable. The risk profile is the same as any freediving site — assuming proper buddy protocol and conservative depth progression.
But you should understand what the cliff face says before you walk past it. This site has killed people. Treat it with the seriousness the plaques demand. Do not freelance. Do not solo. Train with one of the established schools — Freedive International, Dahab Freedivers, or similar — and stay inside their protocols.
Season: March through May or September through November. Avoid the peak summer heat (June–August) and the brief winter cold snap (December–February) when northerly winds can chop the surface.
3 – Amorgos – Greece.
The easternmost of the Cyclades. Less developed than Santorini or Mykonos. A working Greek island with a serious freediving school built into its tourism quietly over the past decade. This is where Saltfree Divers operates — one of the most respected freediving schools in Europe.
The dive sites are walls. The Mediterranean here drops away from the coast in a series of cliff faces and underwater drop-offs that give you 60 to 80 meters of depth within a short boat ride from shore. The water is clear, cold by tropical standards (low 70s Fahrenheit in summer, mid-60s in shoulder seasons), and the marine life is more subtle than the tropics — grouper, octopus, the occasional dolphin, no big sharks.
What makes Amorgos worth the flight is the combination of schooling quality and the Greek-island texture of the trip. You train in the morning, surface, eat lunch at a taverna above the harbor, and the afternoon is yours. The cert is the same anywhere. The experience around it is not.
Luc Besson filmed parts of The Big Blue here in the 1980s. The connection to the sport runs deep on this island.
Season: May through October, with June and September the sweet spots for warm water without summer crowds.
Access: Fly to Athens, then ferry to Amorgos (six to eight hours) or fly to Naxos and connect by smaller ferry. The travel is part of the trip.
4 – Roatan – Honduras.
The Caribbean’s freediving capital. Apnea Total moved their flagship operation here in the late 2010s, after building their reputation on Koh Tao, and the island is now one of the most accessible serious freediving destinations in the Americas.
The geography is what makes Roatan work. A ridge runs along the island’s north shore where the reef drops from 30 feet to over 200 feet within a short swim from the dock. Boats are short rides — five to fifteen minutes from West End or West Bay to a deep line. The water is warm year-round. Visibility runs 80 to 120 feet on most days. The freediving infrastructure — buoys, lines, safety divers — is in place and run by professionals.
Apnea Total runs courses from Wave 1 / Level 1 entry through instructor levels. Their teaching tradition is Molchanov-influenced and known for producing strong recreational divers fast. Three to five days, level-one cert in your hand, 16 to 20 meters under your belt.
The reef here is also better-protected than most Caribbean sites. Roatan Marine Park manages the north shore reef, and while bleaching events have hit, the system is still alive in a way the Florida Keys or much of Belize is not.
Season: March through May for the calmest seas and best visibility. December through April is the dry season. June through November carries hurricane risk but workable dive windows between systems.
Access: Direct flights to Roatan (RTB) from Houston, Atlanta, Miami, Toronto. One of the easier long-haul freediving destinations from North America.
5 – Tulum cenotes – Mexico.
The freshwater cave system under the Yucatán Peninsula. Thousands of sinkholes — cenotes — connecting through an underwater cave network that geologists estimate at over a thousand kilometers of mapped passages, with more being mapped every year. The largest connected underwater cave system on the planet.
The cenotes near Tulum offer something no ocean site does: gin-clear freshwater, halocline layers where fresh meets salt, sunlight pouring through limestone openings in beams that hit the water like cathedral windows. Visibility runs over 100 feet — often closer to 200. The water sits at a steady 76 to 78 degrees Fahrenheit year-round.
For freediving, this is a more technical environment than open ocean. The most accessible cenotes — Dos Ojos, Casa Cenote, the cavern zones of larger systems — are diveable for trained freedivers with a guide. The full cave systems are not. Cavern lines (within direct sight of the surface opening) are appropriate for AIDA 2 or higher with a trained cave-aware instructor. Cave penetration beyond the cavern zone is a separate, technical, scuba-only discipline. Do not confuse the two.
What you get is freediving in a setting that does not exist anywhere else — drifting weightless through limestone halls in light filtered green and gold. The Mayans considered these cenotes gateways to the underworld. Forty feet down, in silence, you understand why.
Season: Year-round. The cenotes are inland, fed by aquifer, and not weather-dependent like ocean sites. November through April are the most pleasant surface conditions. Mid-summer is hot above water but the cenotes themselves are cool.
Access: Fly to Cancún, drive 90 minutes south to Tulum. Several freediving operators in town run guided cenote trips. Freedive Tulum is the most established. Book the guide before you book the trip.
